Explanation:

Allopatric speciation occurs when a population is geographically separated (like the Galápagos islands isolating tortoise groups), leading to independent evolution into distinct species. Parapatric involves partial overlap, sympatric no geographic barrier, postzygotic/prezygotic are reproductive barriers, not speciation types.

Answer:

D. allopatric
